Ondal Ondal+ Shed Roofing and Reinforced Concrete Roofing Systems

The only roofing that allows multiple typological solutions to meet all needs (including shed roofs), while maintaining the essential requirements that modern prefabrication must meet, to ensure the highest level of technical parameters required by both regulations and the most particular design aspects.

The most qualified for the certifications necessary to obtain the prescribed authorizations.

The unmatched example of a structure designed from the beginning to be, as it has been, updated and modified to meet ever-increasing design performance.

Studied, designed, and produced complete with various types of waterproofing in the factory, it creates both flat reinforced concrete roofs and shed roofs. Both types can also be present on the same roof. Natural lighting can, therefore, be obtained flush or through a shed window, particularly designed to ensure both maximum insulation and maximum lighting.
The modularity of the elements allows easy modification of the roof configuration over time if new needs arise. The entire roof, in every detail, offers the highest static, lighting, insulation, fire resistance, and reaction parameters.

Of particular importance is the increasingly requested feature of a large capacity for receiving rainwater in the two main directions of the building, which ensures effectiveness even for sudden short but violent rainfall; in particular, this type offers the greatest capacity compared to any other industrial roofing. On request, it allows water to be conveyed only outside the building (water out). MANINI Prefabbricati guarantees interventions requested within 24/48 hours throughout the national territory.

In the production processes of the large reinforced concrete prefabrication sector, MANINI Prefabbricati, UNIQUE in Europe, has designed and implemented for years, in collaboration with the most important international companies specialized in automation, ROBOTIZED SYSTEMS to guarantee the highest Total Quality of products.

The issues related to CO2 emissions into the atmosphere are well known, which on a global level still question, without effective answers, the entire international community.

Manini Prefabbricati has designed, tested, and verified solutions that allow the creation of natural “green roofs”.

The benefits that these solutions entail are:

Inside a building constructed with the ONDAL structure, the roof offers a view of alternating elements that create architectural plasticity, appreciated for all intended uses of the building itself. This characteristic is even more evident due to the use of a material like reinforced concrete which, without interruption, assuming different shapes, offers a material homogeneity that is unmatched in the prefabrication landscape. Last but not least, this homogeneity, also correlated to the presence of superior continuous insulation, prevents condensation phenomena that, in particular hygrothermal situations, can occur.

The design of a shed roof, never casual at Manini Prefabbricati, has been set to meet the following requirements:

Concrete shell completely equipped with a series of photovoltaic panels, suitably fixed to an intermediate metal frame, already equipped with insulating and waterproofing properties, complete with relative electrical connections.

Linear and compact in form, it is easy to handle in all storage, transport, and assembly operations. The on-site assembly, through a simple electrical connection between the individual shells, eliminates the operations of installing modules at height with significant advantages both economically and from a safety point of view, also achieving a highly prestigious aesthetic value.

The ONDAL+ typology was created to expand the possibilities of using the ONDAL System. While maintaining the variability of the beam spacing between 5.00 m and 7.50 m, the length of the beam can cover up to a column spacing of 32.00 m.

The technical and performance characteristics of this roofing system are similar to those of ONDAL, as well as the production technology of the prefabricated and completion components. Of particular importance is the design possibility to create structural column grids of considerable dimensions: 25.00 m x 25.00 m and, in special cases, even larger.

The macro-advantages of this solution are evident, particularly the following:

Manini Prefabbricati offers various types of edge beams, and to provide further advantages in large-grid solutions, they produce the Super-Omega, which allows for:
